Answer:
1 and 4/35
Step-by-step explanation:
Use distribution property to solve:
6/5 × -5/7 -3/4 -5/7 × 4/5 = -5/7 ( 6/5 - 3/4 ) x 4/5 = -5/7 ( 24/20 - 15/20 ) x 4/5 = -5/7 (-39/20) x 4/5 = 780 / 700 = 1 4/35
Answer:
System is inconsistent and equations are mutually dependent.
Step-by-step explanation:
Let divide each linear equation by its smallest coefficient:


By using the elimination method on variable x, the following equivalence appears:

Since one of the equation is a multiple of the other one, there is not an unique solution and equations are mutually depedent. The system is inconsistent.
5x(8-3)+3x-2
use the distributive property on 5x(8-3)
40x - 15x + 3x - 2
simplify
28x - 2
there's your answer
100%=orignal
increase by 30%
100%+30%=130%
the nwe amount is 130% of old amount
aka old times 1.3=new amount
Answer:
3:1
Step-by-step explanation:
A cone has the same volume formula as a cylinder, except it is 1/3 as much. So to have the same volume, a cone would need to be 3 times as tall.
